Question about LG LCRT2010ST Microwave Oven

1 Answer

Microwave door won't open

My microwave door suddenly stopped opening. It has a push button in the bottom right corner, and if I hold the button for a few seconds sometimes it will open, other times I have to pry it a bit. Doing a quick check around the front housing I don't see any screws that would allow me to open up just this part of the microwave, so I'm assuming I will need to take this thing apart. Anyone know if this is a common issue, and what the most common cause would be? I'm maybe an intermediate level fix-it guy, so need to figure out if I can do this myself!

Often that is due to accumulated grease on the door open button and the opening in the plastic control panel frame in which it moves.

    Thanks...I looked at your links but I didn't get a clear idea of how to fix the issue you suggest. Is there a way to degrease the door open button without removing the chassis? Thanks.

This is a problem with the inverter or magnetron. Due to the lethal voltages involved, I do not recommend that a person without training and experience ever work on these models. You can find support for service or parts at http://us.lge.com/support/support.jsp

SOURCE: take microwave door apart completely

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the previously hidden screws you need to remove.

Or you can watch a YouTube video (not a video I made) here that demonstrates how it's done.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

SOURCE: burning wire smell

Hello jvtmad1,
All of the previous comments are relatively good ideas but let me offer some additional advice,
First off, You need to determine if the burning smell is coming from the Microwave itself or from the receptacle that provides power to it. Most wall receptacles are rated for 15 amps and should easily handle your microwave ovens power requirements. A simple check might be to run a hair dryer on the same receptacle without the microwave plugged into it. They draw comparable power so that should eliminate the recptacle as the culpret, On the assumption that the burnt wire smell is coming from the microwave itself, then your best bet is to return it to the store for a repair or replacement. Unless you are properly trained on how to sservice that, you probably shouldn't attempt it. As stated in previous comments, it should still be under warranty. If you have a bad filament transformer, magnetron or the wiring between them, that is not something you want to fiddle with yourself.
In summary, eliminate the receptacle on the wall as being the problem first.
If you find tha your receptacle is the problem, then you may be able to remove or disable power to it by switching off teh appropriate circuit breaker or fuse.. then take off the face plate and check the integrity of the wires going to that receptacle and making sure they are tightly secured to the terminals of the receptacle. I would assume that if that were the problem, you would notice a burnt smell as soon as you took off the face plate. Hope some of thes ideas help you resolve your problem...
Regards,
Rick

Our LG did the same thing - called customer service and they told us the open and slam the door 10 times. It actually worked! It reset the switches somehow.

Door Spring If the microwave door won't open the door spring may have broken. The door spring is located inside the door and keeps downward pressure on the door hook.

I have a Panasonic Model #NN-S255 microwave oven. The button you push to open the door does not open the door. It's like there is no resistance when you push the button therefore it does not push up...


Hello,To get the door open and salvage your dinner, take a long thin blade ( I used a frosting spreader) and insert from the bottom between the door and the oven frame on the side with the latches (usually next to the control panel). You may have to pry the bottom of the door open just a bit. The object is to push up the lower door latch (which is connected to the upper door latch) and manually open the door. You may have to try a few times but this worked perfectly for me and saved dinner. Obviously the door latch needs to be repaired but this solves the immediate problem of dinner being held hostage by a recalcitrant microwave.
wish you good luck,
take care.

I have a Sharp Microwave Carousel R-420B. I put a bowl of soup in , closed the door, pressed Minute Plus, and hit Stop with approx 20 seconds to go... pressed the door release but nothing happened... door...


Hello,

Usually, the door lever or hinges is the cause of this type of problem.

But in this case, I don't think the door lever or hinge is the cause of your problem.

I think the door is jammed and only needs some force before is can open or unjam.

Use your hands or a flat Philips screw driver to forcefully open the door. Don't apply too much force. Just apply a reason amount of force that could open the oven door.

Before you attempt to forcefully open the microwave door, leave it for about 45mins to 1hr, after that forcefully open the door.

If the above doesn't help to open the door, please let me know so that I can direct you further.

I wish you good luck.

Regards.












Mine does this occasionally, and it's because the door hinges have got a bit out of line, allowing the door to drop slightly, so the catch mechanism won't quite disengage.
Look along the bottom edge of the door and see if it has dropped lower than the front panel next to it. Try applying a bit of upward pressure on the bottom edge with your fingers, while pulling towards you at the same time, and with your other hand press the release button.

If that gets it open, remove last night's failed meal, open the door fully and carefully force it up a bit at a time, to bend the hinges back to level - keep pushing the door back so it nearly closes, and look at the bottom edge to check on progress. When the bottom of the door looks level with the panel , try closing it fully and see if the release button will open it again.

Good luck!

It is a new microwave -- I just took it out of the box. The instructions are in the microwave oven, and I cannot open the door to retrieve the instructions to use the oven. What a birthday present...


Go to sharpusa.com and search for your unit, there you can look or download the instructions manual. I just did and it works. By the way you may check if there is no tape holding the door shut. If there are no obstructions you need to push the "One touch door open button" located at the bottom right corner of your unit if you are in front of it. It may be a little hard initially like many things that are tight when new. Good luck.

Jenn-Air Microwave vent grill opens and closes


I have this same problem occasionally. Pull the vent grill open and look for a white cam that rotates when the microwave is on. To the right of that cam, there are two gray switches. The bottom switch should have a red tab that pops out. When the vent grill opens and closes continuously, the red tab is stuck in. Take a flat screwdriver or tooth pick and push gently in on the red tab to release it. It must get stuck due to grease or dirt accumulation. Good luck.

Unable to open the microwave door since this morning. the oven still works but its closed. when press at the bottom right side corner, the door supposed to be open.


More than likely, the little lever behind the button has broken. You may notice there is less resistance when pushing the button, but perhaps not if your model has a spring behind the button as well. If your handy, you could remove the front panel and take a look at it, but if you dont feel comfortable doing this, it may be equally as expensive to repair this as it would be to buy a brand new one. I'm assuming its out of warranty at this point, but if not, send it back!

Stuck Microwave door


In most cases this is due to a broken door opening lever or loose or broken door latch / hook parts. They can only be accessed and examined if the cover is removed from the microwave. In many over the range models, you can access the door parts by removing the control panel assembly. Sometimes you may be able to get it open by pushing up gently on the bottom of the door while pushing the button, in case you need to empty it.
